Abstract

•Fly ash based geopolymers can effectively solidify heavy metal ions.•The method has low cost and solidification effect is better.•Different heavy metal ions have different influence on the geopolymers.•The solidified mechanism was the physical fixation, adsorption and ion exchange.•The pilot-scale test achieved the same results.
